Lock pose during animation?
I know it's probably too late but maybe it will help someone in the future. I had the same problem and found out that you can key bone constraints during the animation, so after trying a few options I found out that if you apply Limit Location constraint, check all the boxes without changing their values and set Convert to Local With Parent the bone ignores parent and stays in place as if it was &quot;independent&quot;, so the only thing left is to key Influence to 1 whenever you want the constraint to take effect, hope it helps
